Definitions

  • the present invention relates primarily to indoor shoes such as those for volleyball or basketball.
  • lateral bulging may occur, where the foot laterally slides out of the sole, and the input position when vertically kicking the ground is likely to shift toward the ball of little toe as the heel supinates due to the shift of the lower limbs.
  • the present invention includes:
  • wrap W covering a portion of an interior member 1 and formed by a material less stretchable than the interior member 1 , wherein the wrap W includes:
  • a heel portion W 1 continuously covering a medial side M, a back surface B and a lateral side L of a calcaneal bone BC;
  • a twisted portion W 2 having a band-shaped and/or cord-shaped configuration continuous with a front end portion of the heel portion W 1 on the medial side M of the heel portion W 1 , a twisted portion W 2 extending while being twisted on the medial side M of the foot toward under a foot sole;
  • a medial bottom portion W 3 continuous with a front end portion of the twisted portion W 2 , a medial bottom portion W 3 extending along a medial side portion of the foot sole to a ball O 1 of a big toe under the foot sole;
  • a diagonal transverse portion W 4 having a band-shaped and/or cord-shaped configuration continuous with a front end portion of the heel portion W 1 on the lateral side L of the heel portion W 1 , a diagonal transverse portion W 4 covering at least a portion of a cuboid bone BCu and/or at least a portion of a tuberosity (a rough surface) B 5 f of a fifth metatarsal bone B 5 , and further extending across an upper surface of an instep of the foot in a diagonally forward direction so as to cover a portion of an upper surface of the big toe and at least a portion of a side surface of the ball O 1 of the big toe.
  • this loop-shaped wrap W extends, on the medial side M, from the heel portion W 1 via the twisted portion W 2 into the medial bottom portion W 3 reaching the ball O 1 of the big toe under the foot sole, and extends, on the lateral side L, from the heel portion W 1 , covering the side surface and/or the upper surface of the area from the cuboid bone BCu to the tuberosity (the rough surface) B 5 f of the fifth metatarsal bone, and further extends over the instep in a diagonally forward direction, reaching the ball O 1 of the big toe.
  • the loop-shaped wrap W will pull the lateral side L of the heel toward the medial side M both from the medial side M and from the lateral side L, and pull the lateral side L of the instep toward the medial side M.
  • loop-shaped refers not only to cases where the wrap W forms a complete loop (endless), but also to cases where the wrap W is locally discontinuous, e.g., in the area of the big toe. Even if it is locally discontinuous, the pulling effect of the wrap W will be realized as long as it is substantially loop-shaped.
  • less-stretchable material means a non-stretchable material such that the wrap W substantially or essentially does not stretch under a load that can be applied thereon during play. Therefore, a “less-stretchable material” is preferably less stretchable than a foamed resin of a midsole 5 , and is more preferably less stretchable than a rubber outsole 4 .
  • band-shaped includes a belt, and includes a plurality of cords (strings) arranged generally parallel to one another (placed in a parallel arrangement).
  • the “medial bottom portion W 3 extending along a medial side portion of the foot sole” means that a member separate from a sole may be arranged along the medial side portion of the upper surface of the sole or that the portion may be formed by the medial side portion itself of the sole extending along the medial side portion of the foot sole.
  • FIG. 1 is a medial side view showing the principle of the present invention, showing a relationship between the foot bone structure and the wrap.
  • FIG. 2 is a lateral side view showing the relationship.
  • FIG. 3 is a plan view showing the relationship.
  • FIG. 4 is a perspective view showing one embodiment of the present invention, showing the athletic shoe as seen from the medial side, with the exterior member removed.
  • FIG. 5 is a perspective view showing the athletic shoe as seen from the medial side.
  • FIG. 6 is a perspective view showing the athletic shoe as seen from the lateral side.
  • FIG. 7 is a plan view showing the athletic shoe.
  • FIG. 8 is a plan view showing the athletic shoe, with the exterior member pulled open.
  • FIG. 9 is a perspective view showing the athletic shoe, with the lateral-side exterior member pulled open.
  • FIG. 10 is a schematic lateral cross section showing the athletic shoe taken along line X-X of FIG. 4 .
  • FIG. 11 is a schematic lateral cross section showing the athletic shoe taken along line XI-XI of FIG. 7 , i.e., along the diagonal transverse portion.
  • the diagonal transverse portion W 4 includes a first portion W 41 and a second portion W 42 each having a band-shaped and/or cord-shaped configuration; and
  • the athletic shoe further includes a connecting structure J for detachably connecting together the first portion W 41 and the second portion W 42 .
  • the diagonal transverse portion W 4 is provided with the connecting structure J for attaching/detaching between the first portion W 41 and the second portion W 42 . Therefore, the wearer can easily switch between the fastened (tightened) state and the loosened state of the wrap W.
  • the connecting structure J is such that: a tip portion of the second portion W 42 has a through hole W 40 defined therein, through which the first portion W 41 is passed, and a tip portion of the first portion W 41 is inserted through the through hole W 40 and is folded back.
  • the athletic shoe further includes a shoelace 3 for fastening an upper 6 wrapping around the instep,
  • a shoelace 3 is engaged with the folded-back tip portion of the first portion W 41 .
  • the athletic shoe further includes an exterior member 2 covering at least a portion of the interior member 1 ;
  • a portion of the diagonal transverse portion W 4 is arranged between the interior member 1 and the exterior member 2 .
  • the rigidity (stiffness or stiffer) of the upper 6 inevitably becomes large.
  • the wrap W is arranged on the outer periphery of the upper 6 having a large rigidity, the pulling force from the wrap W will unlikely act on the foot.
  • the pulling force of the wrap W acts directly on the foot via the interior member 1 , which is more flexible than the exterior member 2 . This will make it easy to suppress the “lateral bulging” or the supination of the heel.
  • the wrap W is unlikely to be exposed over the exterior member 2 , and the wrap W will not possibly hinder play.
  • the interior member 1 includes a lateral-side interior member 10 in contact with a lateral side surface of the foot;
  • the exterior member 2 includes a lateral-side exterior member 20 covering the lateral-side interior member 10 ;
  • a portion of the diagonal transverse portion W 4 is arranged between the lateral-side interior member 10 and the lateral-side exterior member 20 .
  • the wrap W is hidden between the interior member 1 and the exterior member 2 , and the wrap W will not hinder other players during play.
  • interior member includes a member, as a part of the tongue, arranged on the medial side M or the lateral side L of the foot.
  • the lateral-side exterior member 20 is not attached to the lateral-side interior member 10 ; and a plurality of engagement portions 27 , with which the shoelace 3 for fastening an upper 6 wrapping around the instep, are provided in a non-attached portion 201 of the lateral-side exterior member 20 that is not attached to the lateral-side interior member 10 .
  • the lateral rigidity of the upper 6 is increased by the lateral-side interior member 10 and the lateral-side exterior member 20 , while facilitating the dorsal flexion of the foot.
  • the lateral-side exterior member 20 has a cutout (notch) 29 extending downward from an upper end of the lateral-side exterior member 20 .
  • the cutout 29 further facilitates the dorsal flexion of the foot.
  • the athletic shoe further includes an attached portion W 10 where the lateral-side exterior member 20 is integrally attached to the lateral-side interior member 10 in the heel portion W 1 ; and
  • the attached portion W 10 having a high rigidity improves the heel holding property, while the movement of the middle foot portion is unlikely to be hindered because of the non-attached portion W 11 having a low rigidity.
  • the athletic shoe further includes:
  • twisted portion W 2 and the diagonal transverse portion W 4 are formed by a band-shaped and/or cord-shaped (string-shaped) member that is less stretchable than the midsole 5 .
  • the athletic shoe further includes:
  • a sole having a plurality of cleats of which a primary component is a leather or a non-foamed material (a non-foam body) of a synthetic resin;
  • medial bottom portion W 3 is formed by at least a portion of the sole.
  • the cleats are formed by a non-foamed material of a synthetic resin or by a metal.
  • the sole of a leather or a non-foamed material of a synthetic resin having a large rigidity may function as the medial bottom portion W 3 , and it may not be needed to separately provide a member for the medial bottom portion W 3 .
  • an upper 6 wrapping around the instep includes the interior member 1 and an exterior member 2 that is less stretchable than the interior member 1 ;
  • a lower edge of the exterior member 2 extends along an inner surface of an upper edge of a sole
  • the lower edge of the exterior member 2 and a portion of the sole form at least a portion of the medial bottom portion W 3 .
  • the lower edge of the exterior member 2 that is less stretchable and a portion of the sole form at least a portion of the medial bottom portion W 3 , which will allow for a lower cost as compared with a case where a non-stretchable material to be the medial bottom portion W 3 is provided separately.
  • the sole includes:
  • a reinforcement member 7 attached to the midsole 5 along an arch MA at least on the medial side M of the foot for preventing the arch of the foot from lowering, wherein the midsole 5 is reinforced by the reinforcement member 7 , thereby reinforcing the medial bottom portion W 3 .
  • the medial bottom portion W 3 is reinforced by the reinforcement member, thus making it easy to suppress stretching or bending of the medial bottom portion W 3 .
  • one end portion of the diagonal transverse portion W 4 extends from a side surface of the ball O 1 of the big toe so as to slip under the ball O 1 of the big toe, and extends along an upper surface of the sole (shoe sole) so as to cover at least a portion of a bottom surface of the ball O 1 of the big toe.
  • the sole includes a roll-up portion 50 rolled up on a medial side of a middle foot section; and
  • the front end portion of the twisted portion W 2 extends along an upper surface of the roll-up portion 50 so as to slip into (get into) between an arch MA on the medial side M of the foot sole and the roll-up portion.
  • the front end portion of the twisted portion W 2 is sandwiched between the arch of the medial side of the foot and the roll-up portion of the sole, and the front end of the twisted portion W 2 of the wrap is held down by the arch on the medial side of the foot, thereby increasing the effect of suppressing the “lateral bulging”, etc.
  • the expressions “along the upper surface of the sole” and “along the upper surface of the roll-up portion” include cases where one end portion of the diagonal transverse portion W 4 or the front end portion of the twisted portion W 2 is in direct contact with the upper surface, and also include cases where the exterior member 2 , or the like, is interposed between the upper surface and the wrap. Thus, it will typically be a structure where a portion of the wrap is layered on the upper surface.
  • the diagonal transverse portion W 4 extends spirally and continuously along a surface of the instep along a path to a portion of the upper surface of the big toe starting from an area covering at least a portion of the cuboid bone BCu and/or at least a portion of the tuberosity (the rough surface) B 5 f of the fifth metatarsal bone B 5 .
  • the term “extend spirally” means that while the surface of the instep is a complicated curved surface, the diagonal transverse portion W 4 extends along the curved surface so as to be diagonally wound around the curved surface.
  • the term “extend continuously” means that where the diagonal transverse portion W 4 is completely divided between the medial side and the lateral side and an ordinary shoelace connects together the medial side and the lateral side of the upper, the ordinary shoelace itself does not form the diagonal transverse portion W 4 .
  • shoelace is an essentially or substantially non-stretchable shoelace and if the shoelace is arranged along the spiral pattern, that shoelace forms a part of the diagonal transverse portion W 4 .
  • the wrap W includes the heel portion W 1 , the twisted portion W 2 , the medial bottom portion W 3 and the diagonal transverse portion W 4 . Note that in FIG. 1 to FIG. 9 , the wrap W is shaded with fine dots.
  • the heel portion W 1 continuously covers the medial side M, the back surface B and the lateral side L of the calcaneal bone BC.

  • the majority of the second portion W 42 is arranged between the first lateral-side exterior member 21 and an integral member including the lateral-side interior member 10 and the second lateral-side exterior member 22 .
  • the second portion W 42 is attached to the outer surface of the lateral-side interior member 10 and the second lateral-side exterior member 22 attached to each other.
  • the majority of the first portion W 41 is arranged between an integral member including the tongue-shaped interior member 1 T and a cushioning member 1 C attached together and an integral member including the medial-side interior member 1 M and the medial-side exterior member 2 M attached together.
  • An upper portion of the first portion W 41 is exposed through an opening in the upper 6 between the medial side and the lateral side.
  • first portion W 41 shown in FIG. 4 may be intermittently sewn onto the cushioning member 1 C.
  • the lower end portion W 43 of the first portion W 41 extends along the upper surface of the midsole 5 and extends from the side surface of the ball O 1 of the big toe so as to slip under the ball O 1 of the big toe so that at least a portion of the reverse surface of the ball O 1 of the big toe of FIG. 1 is covered.
  • the lower end portion W 43 is preferably arranged along the upper surface of the midsole 5 so that the stepping force from the ball O 1 of the big toe acts upon the lower end portion W 43 of the first portion W 41 .
  • the medial bottom portion W 3 is formed by a part or whole of the sole 4 A.
  • the medial bottom portion W 3 is formed by the midsole 5 , the reinforcement member 7 for reinforcing the midsole 5 , and the outsole 4 .
  • the medial bottom portion W 3 is reinforced.
  • the lower end portion W 43 and the reinforcement member 7 are connected together by the outsole 4 and the midsole 5 , whereas the front end portion W 21 and the reinforcement member 7 are connected together by the midsole 5 . Therefore, the midsole 5 at these connecting portions (mainly the roll-up portion 50 ) may stretch slightly. However, during an action which may lead to the “lateral bulging”, a strong compressive force acts upon the connecting portions, and therefore substantially no such stretching will occur.
  • a portion of the wrap W (the medial bottom portion W 3 ) does not need to be formed by a non-stretchable material, but portions of the wrap W that are wrapped around the upper 6 (the heel portion W 1 , the twisted portion W 2 and the diagonal transverse portion W 4 ) are preferably formed by a non-stretchable material.
  • the lower edge of the medial-side exterior member 2 M extends along the inner surface of the upper edge of the sole 4 A, and the lower edge of the medial-side exterior member 2 M and a portion of the sole 4 A form at least a portion of the medial bottom portion W 3 .
  • the medial bottom portion W 3 is formed by at least a portion of the hard sole.
  • the first lateral-side exterior member 21 is not attached to the lateral-side interior member 10 and the second lateral-side exterior member 22 .
  • a plurality of engagement portions (through holes) 27 with which the shoelace 3 engages are provided in the non-attached portion 201 of the first lateral-side exterior member 21 that is not attached to the lateral-side interior member 10 and the second lateral-side exterior member 22 .
  • the first lateral-side exterior member 21 has a cutout 29 of a V-letter shape, a trapezoidal shape, or the like, extending downward from the upper end of the first lateral-side exterior member 21 .
  • the wrap W arranged as shown in FIG. 5 to FIG. 7 fastens the foot as the shoelace 3 is inserted through the cord-passing hole J 0 with the first portion W 41 and the second portion W 42 engaged with each other.
  • a substantial side brake acts on the medial side of FIG. 4
  • the lower end portion W 43 of the first portion W 41 and the front end portion W 21 of the twisted portion W 2 are sandwiched between the foot sole and the sole 4 A on the medial side of the foot. Therefore, on the lateral side of the foot of FIG. 6 , the loop-shaped wrap W suppresses the “lateral bulging”, the supination of the heel portion, etc.
  • the connecting structure J may be a belt of which the male surface and the female surface engage with each other.
  • the wrap W is band-shaped except for the medial bottom portion W 3 in the present embodiment, the wrap W may be formed by a plurality of cords arranged parallel to each other.
  • the diagonal transverse portion W 4 and the twisted portion W 2 may be inserted between the outsole 4 and the midsole 5 .
  • the diagonal transverse portion W 4 and the twisted portion W 2 may be inserted between the two layers of the midsole.
  • the lower end portion W 43 of the diagonal transverse portion W 4 and the front end portion W 21 of the twisted portion W 2 may be secured to the midsole by means of a fastening device such as a bolt and a tacker (stapler).
  • a fastening device such as a bolt and a tacker (stapler).
  • the lower end portion W 43 of the diagonal transverse portion W 4 and the front end portion W 21 of the twisted portion W 2 do not need to be slipping under the foot sole, and there may instead be provided an exterior member, at the lower end portion of the medial side surface of the upper 6 , for connecting together the diagonal transverse portion W 4 and the twisted portion W 2 .
  • the non-stretchable member of the wrap W may be a combination of a band and a plurality of cords, or may be a band whose width is partially widened or narrowed.
  • the diameter of the holes provided in the upper 6 for allowing the shoelace 3 to pass therethrough may be made smaller than the diameter of the shoelace 3 . In such a case, the shoelace 3 can move less easily so that the fastened state of the connecting structure can be maintained more easily.
  • the structure of the present invention may be applied only to a shoe for the pivot foot (pivoting foot), or the structure of the present invention may be applied to both feet.
  • the present invention is applicable not only to indoor shoes for volleyball, handball, etc., but also to shoes for outdoor sports.
